The present invention relates to a functional luminaire that can extend the life of the luminaire by dissipating heat generated in the luminaire to the outside.
In general, street lamps are lighting facilities installed along streets for the safety and security of street traffic, and suitable types are used depending on installation places such as highways, main roads in downtowns, commercial roads, and residential district roads.
There are several types of streetlight poles, such as the highway type that bends the end of the pole and has its back at the end, a bracket that extends horizontally at the end of the pole, and has a back on it. There is a head-mounted lamp, and a high-pressure mercury lamp, a fluorescent lamp, a sodium lamp, a light bulb is usually used.
1 is a view showing a conventional lamp for streetlights.
Conventional streetlight luminaires, as shown in Figure 1, is provided with a light emitting means (not shown) therein, consisting of a
Accordingly, the light generated by the light emitting means such as a light bulb is transmitted through the
In addition, the upper casing 100a and the lower casing 100b may be connected to each other by the hinge means 140 to open the other side for maintenance of the luminaire, and fastening means 500 such as a clip or a ring. The coupling state is maintained by, and one side of the upper casing (100a) is a structure for fixing to the electric pole, the
However, a conventional lamp for a street lamp emits high temperature heat when the light emitting means emits light. This heat causes a problem of damage to an electric device such as a light emitting means or a wiring in the casing.
In addition, if the through-hole is simply formed in the casing to cool the heat generated in the conventional casing, worms are introduced into the casing, and water or moisture is introduced into the casing, causing various damage to the luminaire. There was a technical problem.
On the other hand, in order to solve the above problems have been proposed "street lamps" (Utility Model Registration No. 0371524) registered in advance on December 20, 2004. same.
Conventional streetlight luminaires are provided with a light emitting means therein, a luminaire made of a casing including a transparent window on the lower surface, the through-holes respectively formed through the upper and lower surfaces of the casing so as to distribute the air inside and outside the casing; A carbon filter filled in the vent hole; A hemispherical cap spaced apart from the upper surface of the casing in a predetermined height upward direction; A lower end is formed in communication with the upper vent hole of the casing, and the vent pipe in which the upper opening is located inside the cap is further configured.
However, the conventional streetlight luminaire is a heat dissipation depending on the air naturally distributed in the casing, there is a structural problem that the heat dissipation is not properly performed on a low wind.
The present invention has been made to solve the problems of the prior art, an object of the present invention to provide a functional luminaire that can easily release the heat generated from the lamp and the ballast to the outside by using a heat dissipation unit.
The present invention for realizing the object of the present invention and the case; An installation table provided at the rear of the case; A lamp connected to the mounting table; A ballast for stabilizing a current flowing through the lamp; A reflector positioned above the lamp to reflect light of the lamp; A glove which closes the lower part of the case and transmits light of the lamp; And a heat dissipation unit for dissipating heat from the ballast and the lamp to the outside.
Hereinafter, embodiments of the present invention will be described based on the drawings.
